There are various-modesfot pressing and spraying processes to which the operator may resort-in the use' "of'thispress.rv l Y lhe mayg leave the vvalve 45446 normally ward compression movement against the work on the buck 6.

` The jaw 7 and press Aplate 33 are held together for relative motion by any suitable means, as for example by abolt 37 .anchored at 38 tothe press-plate 32-33 and thebolt is j press plate retaining ymeans 37--1-40l may be used, as for example one at each endo'tl the press' head. `f x The lsteam yorv iluid pressure admitted intofthe-heating chamber 14 is also admitted directly into the compression chamber l21 by pulling" downwardly on thevalve handle `24. In this way the valve stemv 2 3 is lifted oit' the valve seat `oriiicef20' andl steam or air flows .then intothe compression chamber 21 thus causing the diaphragm 27 to move downwardly which actsrto slide'fthe press plateV 33 in the jaw guide'12-1to produce pressureon the ff-bucki -Tlji'e -a/'allve'handle 24 is' imnied-iately released and vthe fiuidpressure remains in the compression chamber 21 tofliold thepress plate down 'to produce-jaw compression until' "afterfthe pressing'operation hasactually been whereupon the operator f may release the jaw compression through the 'other control means which will now be described.

"lllie'press` plate 32gis formedwithv a fluid passage43`which is open at rthetop 'to com- `nii-unieate with ythe compression chamber 21 and which is closed )at thebottom, but is provided near thevbottom with a valve seat orifice 44 leading outwardly into 'the spray f charnberi oftl vthe pressureplate 33.` This `valve orifice/14 is closed by avalve stem 45 whichisreciprocated by a valve handle 46, and thelatter` parts arepreferably spring lactuated 'so as to normally niai'ntain the valve seat 44in closedcondition. The `operator `may kpressthe val\fe7liar1dle 46 to open the oriliee '44 thereby: exhausting' lluid vpressure mrfthe compression chamber-2l into the V*spray chamber 34 and hen-ce onto the work which rclicvesthe expanded yor bulged tension otfthe diaphragm 27-just at the instant tbefworlr is steam sprayed or air sprayed thereby Vpermittinw the spraymedium to be 1h v impregnated in the abric of the goods tobe through pipes 1l and through `apertures -15 `rWea-iss closed wlienflie first closes the press head 7 f Y .()n the other liand, the operator mayop'en the valve thereby sprayingthe workafter it hasreceived a fewfseconds oiY dry pressing, or he may simultaneously-'open both valves24 and 46 thereby spraying and pressing the work at one and the same time.

Opening thespray valve 46slightlyrand the jaw compression valve 24 fully maintains the diaphragms in extended position to eflect jaw compression desp-ite the fact thata small quantity of steam is flowing into the work. Thereafter the luid pressure is eX- vliausted from the diaphragm chamber 21 by any approved means, and the springs 4() then lretract the pressure plate and hence compression is removed from the work on the buck. Y

After the pressing operation and exhaust of fluid pressure from the diaphragm Vchamber, the anchorage means 40, which' holds stantly pulls upwardly on the Vbolt 37 to remove the pressureplate from the work and returns the diaphragm 27 to normal nonpressing position as shown in the drawing.

A pressing machine of this character is simple in lconstruction and easy to operate and there is no exposed mechanism carried on the frame of the machine and all movable parts are concealed.

It is observed that the pressure plate iiuid entry passage 43 leads through the diaphragmV 27 andthat the diaphragm may be sealed on the plate 32 in any suitable way as at'31. The heating chamber 14 is curved upwardly at 13 to bring the compression n cliamber- 21 and the -two sealing means 29 and 13 iiito alignment with the chamber 14.

. The valve 16 is located at the highest point Aolf the heating chamber and therefore discharges the dryer steam held in the chamber 14 down into the spray chamber for steamtreating and moist-eiii'ng the work. The plate 31 is anchored by screws oi' other means to the wall 32 and seals the diaphragm to-said v wall. A screw plug 31al provides an open-Y ing through the upper vwalls '18, and v19'to insert and secure the plate 31 in place. The active or power jaw7 in its simplest form consists of a stationary part 7 and the relatively slightly movable pressure plate 32--33which is `forced downwardly toi produce aw compression bythe motor means 27, thev pressure plate including means -to air-spray or steam-spray the Work. The stationary part or member 7 includes the two :chambers 21 and'14, one under the other,` while the pressure member or plate 32-33 inf eludes the enel air-or steam s'prayor suction chamber 34. Thel diaphragm 27 isoftlie `flat-circular plate or disk type andk being iny, lierently flexible and: attached to .both the stationary and 'movable member, completes the structure of the compression chamber 21, Y which isv formed between the two-main rela# j tively movable jaw members ..7 and 33.

The yielding connecting oranchorage means 40 retracts the compression plate 32-33linto close engagement with the Ylieat-fm ing chamber 14 of the other plate 19,-tlier .member 18-19 forming a support for.' the movable presser plate. The two comple- Vmental parts or plates have their adjacent walls 19 and 32 indirect surface con-g8 tact throughout the complemental area of the two Ycooperating relatively i movable plates.
